ABSTRACT:
A liquid crystal display device includes a reflector disposed at an outside surface side of one substrate of a liquid crystal cell or between the first substrate and an electrode disposed on an inside surface side of the first substrate. When an angle between a direction of a normal line with respect to a display surface of the liquid crystal display device and a main viewing direction is from about 0 degrees to about 20 degrees, a reflection ratio peak value of light incident upon the liquid crystal display device and reflected by the reflector is set so as to occur within a range of about 20 degrees from the normal line direction.
